rlhis invention relates to a composite lath or sheathing material for use in building constructions, one of the objects being to provide an inexpensive and durable structure to which plaster or stucco can be applied readily, the plastic material being adapted to anchor firmly to the lath.

A further object is to provide a means for holding the soft plastic material from creeping after being applied and before it has set. v

l/With the foregoing and other objects in view which will appear as the description proceeds the invention resides in the ccmbination and arrangement of parts and in the details of construction hereinafter describedy and claimed it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

ln said drawings, Figure l is a front elevation of a portion of a structure such as constitutes the present invention.

Figure 2 is a section therethrough on line 2-2, Figure l. Referring to the figures by characters of reference 1 designates a layer of corrugated paper board. lf preferred two or more layers of this material can be used. Stretched over the outer surface of the paper board is a coarse net 3 formed of jute or other fiber and provided with relatively large knots 4L at the angles of the mesh. Overlying the net 3 is a Coarse wire fabric. The several parts constituting` the lath are adapted to beheld to the wall W by nails 6 having large heads. After the different thicknesses of material have been assembled and attached as described, the plaster, stucco, or other soft plastic material is applied in the usual way. The channels provided by the corrugated board will allow the plastic material to anchor back of the net and the wire fabric and the coarse net will hold the material against `creeping before it becomes set. Thereafter the wire fabric will act as a reinforcement for the set plaster Ior stucco. The corrugated board is advantageous not only because of its cheapness but also because it provides air cells which tend to insulate the wall.

lt has been found in practice that, in order to render the lath moisture proof, it is preferred to treat the corrugated board with paratline or other water-proofing material.

llhat is claimed is:

A device of the class described including a thickness of corrugated paper board, a fibrous net screed thereover, a metal fabric spread cv-r the fibrous net, and fastening means having portions engaging the metal fabric to bind said fabric upon the net and to bind the net upon the board, said fastening means extending through the board for engagement with a supporting structure7 the spaces between the corrugated board and the fibrous net and between the fibrous net and the meta-l fabric being adapted to receive a plastic material applied to the device.

In testimony that I claim the foregoing as my own, l have hereto axed my signature.

JAMES P. BEATY.
